BUILDING FORMED OF PRECUT, FOLDABLE SITE ERECTED PAPER BOARD PANELS This application is avcontinuation in part application of application Ser. No. 195,139 filed Nov. 3, 1971, and identically entitled, now abandoned.

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a new and novel method in the construction of buildings and, in particular, to paper board, triangular roof trusses, identical trapezoidal side wall and roof panels, and rectangular end and side panels used in the construction of houses, storage sheds, garages, motels, etc.

2. Description of the Prior Art Reinforced, waterproof paper board sheet material has been employed in the construction of various types of buildings in recent years, taking the form of roof and side panels having structural rigidity and capable of sustaining normal loads. This has resulted in the construction of buildings formed almost entirely of paper board panels without the necessity of conventional metal or wood frames allowing on site erection or assembly of prefabricated modular sections premanufactured at factories remote from the building site.

One form of such paper board building makes use of modular panels in which the panels are precut from sheet material and provided with fold lines defining the various walls of the modular panels and provided at the ends with tabs such that on site formation of the panel consists of bending the sheet about the fold lines and fastening the panel walls together by stapling the overlapping tabs and/or walls. A panel consisting of at least one center wall and opposed right angle side or edge walls forms a modular panel with sufficient rigidity that it may be employed in conjunction with other panels to form roof and side wall sections of inverted U-shape. The U-shaped sections known as tunnels are then joined end to end by fastenings such as by stapling the abutting side or-edge walls, and multi-ply, inverted, edge abutting U-shaped tunnels have their ends coupled to a floor or other foundation to form an angular rectangular building structure.

While paper board buildings constructed in such a manner have allowed fabrication of the panels from precut and scored sheets delivered to the erection site, to reduce cost in transporting of the building material, and while the modular building formed thereby may be constructed in a relatively inexpensive fashion by unskilled labor, paper board structures of this type to date lack the structural integrity at the load centers to allow such buildings to be built of comparatively large size. Further, the ability of such building panels to withstand adverse weather and other climatic forces are highly questionable.

SUMMARY OF THE INVENTION The present invention is directed to an improved building structure formed of precut, foldable, site erected, fiberglass reinforced, resin-coated paper board panels in which multi-ply panel walls are provided at various load centers without compromising the simplicity in design and ease in assembly of the panels to form the building. The present invention further allows the paper board panels to take the form of triangular roof trusses and vertical rectangular end and side panels which are provided with optional internal walls in various expeditious manners.

Preferably, the building structure is formed of a plurality of prefabricated abutting fiberglass reinforced, resin-coated paper board panels with their sides fastened together to form a complete building side wall. The improvement resides in each side wall panel comprising at least one side wall having hinged end walls extending at right angles along the sides of the same to define stud flanges. In one embodiment, the side wall panel extends at one end beyond the ends of the edge walls and bears four fold lines defining three side wall extension portions, and, in that order, the first two are folded back on themselves and are of equal dimensions in the direction along the length of the panel to form a two-ply end wall with the third panel side wall extension portion acting as an extension of the side wall itself, lying coplanar therewith, and being at right angles to the two-ply end wall to thereby facilitate fastening of the panel at that end to a building foundation or base in mutually distinct right angle planes. Two tabs may extend outwardly on each side of one of the first two side wall extension portions for attachment to respective edge walls in mutually overlapping engagement to rigidly locate the edge walls at right angles to the side and form a rigid load bearing member.

The invention is further directed to a roof truss assembly consisting of two series of abutting end-to-end fastened, oppositely directed boxed end roof truss panels. Each panel is formed of a single sheet of fiberglass reinforced, resin-coated paper board material including fold lines defining -a central, rectangular roof portion or central wall, and at least two side walls of trapezoidal shape extending along respective sides of the center wall. Aligned fold lines near one end of the center wall and side walls define tabs which mutuallyoverlap when the side walls are folded at right angles to the center wall. The length of the center wall tab is less than the full width of one of the side wall tabs and the other side wall tab extends from its outer edge inwardly a length equal to the difference between the length of the edge from which it extends and the length of the center wall tab. The other end of the center wall extends beyond the ends of the side wall and carries fold lines to define three center wall extension portions, the first having a length equal to the height of the side wall at that end, and when folded abuts the same to form an end wall, said second center wall extension portion defining a bottom wall for the boxed end truss panels and the third center wall extension portion projecting downwardly and at right angles to the bottom wall of the truss panel to facilitate fastening of a side panel thereto. With oppositely directed roof truss panels being fastened end to end, there is formed a four-ply king post of high structural integrity, capable of supporting heavy loads.

The invention is also directed to a building structure in which the sides and roof and formed of multiple series of end to end connected identically configured panels, with each panel being formed of a single paper board sheet and comprising at least one center wall with integral side walls extending the length of the center wall and contiguous tabs extending from coextensive ends of said center and side walls as defined by fold lines therein, such that the center wall tabs are rectangular in configuration, while the side wall tabs are trapezoidal in configuration. The side wall tabs are defined by fold lines inclined inwardly of the center wall tab fold line, with the side wall tabs being of a length equal to one-half the width of the center wall tabs such that when the end walls are folded at right angles to the center wall for each panel, in the same direction, and the center wall and side wall tabs are also folded at right angles in the same direction, the tabs lie in mutually overlapping positions to define a four-ply king post or girt connection between the end abutting panels.

In one form, the building structure is characterized by a series of horizontal roof panels which join at respective ends, oppositely inclined series of side wall panels, while front and rear walls comprise side wall abutting panels having identically formed multi-ply ends to theroof panels and the side wall panels. Alternatively, the building structure may consist of four side wall abutting series of panels which are trapezoidal in elevation with the series of panels in end to end abutment such that the outer two series of panels are inclined inwardly at an acute angle with respect to a horizontal support surface, while the inner two series of panels end abut each other and to the respective outer two series of panels to define obtuse angles therebetween. Further, the smaller ends of the outer two series of panels abut the horizontal support surface, while the smaller ends of the inner two series of panels abut each other to define the roof center, while the larger ends of both the inner and outer series of panels abut each other to form a four-ply, large surface area load center girt connection.

Panels may be fastened to other panels, tabs to side or end walls or tabs to each other in mutually overlapping fashion, by means of sheet metal fasteners consisting of metal strips on opposite sides of the paper board panel layers being coupled. The fasteners have projections or barbed prongs struck out of the same extending outwardly at right angles to the plane of the metal strip. The prongs have pointed ends and serrated sides defining barbs and are received within the hexagonal openings of the opposed metal strip. The serrations permit easy entry of the barbed prong within the hexagonal opening but resist retrograde movement. The height of the prong and the length of the barbed area permit the oppositely oriented, dual metal fastening strips to be applied to overlapping paper board sheets in layers numbering two or more.

DESCRIPTION OF PREFERRED EMBODIMENTS One embodiment of a high strength completely fiberglass reinforced, resin-coated paper board building constructed principally with the roof truss and side panels of the present invention is illustrated in FIG. 1.

4, 2 X 8, 2 X 10 board, or the like, with the top of the plate 16 lying flush with the top of the floor slab 12 and the side 20 of the mounting plate lying flush with the side wall 22 of the foundation. The front, rear and side walls of the building may be specially formed of panels 24 of rectangular configuration, hereinafter called side wall panels, while the roof comprises a roof truss assembly 26 consisting of two rows of side-to-side abutting, and end-to-end abutting, oppositely directed boxed end roof truss panels 28, the roof truss panels preferably being of a width commensurate with the width of the side wall panels 24. In the particular building illustrated, a rear wall is shown as being formed of panels 24 identical to the side wall panels with the exception that certain panels have been formed with openings 30 to receive window units 32 in conventional building construction fashion.

The special nature and construction of the roof truss panels and the side wall panels 28 and 24, respectively, may be best seen by reference to FIGS. 2, 3 and 4. Both the roof truss panels and the side wall panels are modular in nature, that is, a plurality of identically configured and formed panels 24 are fastened together in side-to-side abutting fashion to form the side and end walls, while identically formed and configured roof truss panels 28 are fastened together in a pair of oppositely directed longitudinal arrays, that is, from front to back in FIG. 1, the elevational configuration of the roof truss panel being trapezoidal in form with the ends of greater height abutting each other at the center and forming the king post 98.

The material forming the modular panels 24 and 28 is designated as being paper board and as such may consist of a corrugated board formed of paper or its equivalent and suitably waterproofed such as by being fiberglassed and resin impregnated, resin coated or by other conventional means. The present invention is not directed to the particular board forming the panel material, but rather to the structural and configurational details of the panels themselves and the method and means for fastening either the panels together or the portions of the sheet material forming the panels together, to complete a panel of high structural rigidity and strength. If necessary, subsequent to their formation and prior to or subsequent to their assembly into a completed building wall'or roof, the outer surface of the panels 24 and 28 may be further reinforced and treated with resin impregnated fiberglass mat which is highly weatherproof.

Turning to FIG. 5, each roof truss panel is formed in the preferred arrangement from a single sheet 34 of f1- berboard and comprising in terms of scored fold lines indicated by the dotted lines in FIG. 5 of a roof portion or center roof panel 36 of rectangular configuration, trapezoidal side walls 38 and 40 extending along respective sides of center wall 36, and an optional ceiling flap 42 of like configuration and dimensions to the center wall 36 and being joined to the outside of the side wall 40. At the right hand or inboard end of the roof truss sheet 34, integral tabs are defined by contiguous scored fold lines to form tab 44 as an extension to center wall 36 and of a width equal to the same and of 'a length less than the width of tab 46 which forms an integral extension or projection of side wall 40. Tab 48 has a width less than the full width of panel side wall 38, at that end, but is equal to the difference between the length of tab 44 and the full width of tab 46 such that, as indicated in FIG. 6, when side walls 38 and 40 are folded at right angles to center wall 36 and extend in the same direction and in turn when tabs 46 and 48 are folded into planes in mutually overlapping fashion and when tab 44 is bent downwardly at right angles thereto, the free edges 50 and 52 of tabs'48 and 44 are in mutually abutting position and tabs 44 and 48 overlap respective portions of tab 46, FIG. 6. As shown, the optional ceiling flap 42 may then be bent inwardly and at right angles to the side wall panel 38 to form a trapezoidal-hollow box. If desired, thermal insulation may fill the panel and 2 X 4 reinforcers 54 may form cross pieces at spaced longitudinal positions to give greater structural rigidity to the formed roof truss panel 28.

The present invention is further directed to the manner in which the roof truss panel is provided with an integral, formed box overhang or sectional soffit at the left hand side or outboard end of panel 28 as illustrated in FIG. 6. In this respect, the center wall 36 has three center wall extension portions, extending outwardly beyond the ends 56 of side walls 38 and 40 in order at 58, 60 and 62. Further, the center wall extension portion 60 is provided with integral tabs 64 extending outwardly at right angles to the longitudinal axis of the panel at the sides thereof. During set-up to form the completed panel of FIG; 6, center wall extension portion 58 is folded inwardly at right angles to form an end wall, the larger area wall extension portion 60 forms the bottom soffit of the box overhang, while wall portion 62 extends downwardly therefrom and at right angles thereto to facilitate coupling of a formed side wall panel 24 thereto at its upper end as best seen in FIG.

Further, tabs 64 are received within and extend upwardly on the inside of and adjacent toside walls 38 and 40 of the panel and are fastened thereto in the same mariner as the other tabs forming the precut, roof truss panel 28. In this respect, staples may be employed to fasten the end tabs to overlapping tabs or wall portions of the panel, but preferably metal strip fasteners 110 illustrated in FIGS. 9 and 10 are employed for these purposes. In addition, epoxy adhesives or like waterproof glues may be employed in lieu of or in conjunction with metal fasteners to fasten the walls and tabs in position.

The present invention is further directed to the improved side or end panels for use in the building structure of *FIG. L In this case, as illustrated in FIG. 7 a sheet 66 of paper board is precut and includes scored fold lines as indicated by the dotted lines to effectively produce when set up the side and end panel of FIG. 8. The modular side or end panel 24 includes a center or side wall 68 facing the exterior, with fold lines defining on either side thereof, edge walls 70 and 72 forming stud flanges with an optional interior wall flap 74 being integrally formed therewith and extending from one of the edge walls such as 72 and being of a length on the order of the edge walls. Fold lines further define a center wall extension portion or tab 76 at the upper end and three fold lines at the bottom end of the same center wall 68, define center wall extension portions 78, 80 and 82, in that order. Center wall extension portion 78 carries tabs 84 of a width on the order of the width of edge walls 70 and 72 which extend outwardly therefrom. During set-up, the edge walls 70 and 72 are folded at right angles to the plane of the center wall 68 and in the same direction, panel center wall extension portion 76 folds at right angles to the plane of the center wall 68 and towards the upper edges of the edge walls 70 and 72 and are suitably joined thereto by fastening to tabs 77 which are folded at right angles to edge walls 70 and 72 and lapped over 76, at the top. Center panel extension portion 78 folds at right angles to the plane of the center wall 68. Center wall extension 80 is folded at right angles to portion 78 after folding tabs 84 at right angles to said extension 80 to form a box-like structure of maximum rigidity, when fastened together. Further, the second center wall extension portion 80 folds back on itself, that is, it lies flush with center wall extension portion 78 to form a two-ply end plate while the lower and third center wall extension portion 82 projects away from the end wall formed thereby to define a flap which lies coplanar with the center or side wall 68. The optional interior wall flap 74 may be closed upon the free edge of the stud flange 70 to complete a closed side or end panel, preferably after thermal insulation is placed therein and after the installation of electrical wiring, plumbing or the like.

From the above description, the construction of a complete building, in one embodiment, employing principally these two preformed and specifically configured panels may be readily apparent. Further, the improved structural integrity and load bearing capability of the panels may be visualized by reference to FIGS. 2, 3 and 4. Anchor bolts 86 extend upwardly, with ends buried in the foundation side walls 22. Their threaded ends pass beyond the surface of the edge mounting plate 16, through aligned holes within the two-ply side wall panel extension portions 78 and 80.

Coupling of plate 16 is completed by means of a threaded nut 88 and underlying washer 90.

Turning to FIG. 3, it is noted that, if necessary, a reinforcing plate may be epoxy glued and stapled or otherwise affixed to either or both side edges of the panel stud flanges. In this case, reinforcing plates 94 extend upwardly into the roof truss panel 28 with their lower ends within the side wall panel 24 and are stapled respectively to the edge walls or stud flanges 70 and 72 and to the side walls of the roof truss panel 28. In lieu of staples 99, the special strip fasteners 110 of the present invention as illustrated in FIGS. 9 and 10 may be employed. It is noted that sealed joints are provided between the bottom end of the side wall panel and its foundation and the top or upper end of the side wall panel and the truss panel 28 to form the box overhang. In this respect, the end flap 62 of the truss panel center wall 36 overlies, is sealed to and mechanically affixed, to the upper end of the side wall panel center wall 68. In addition to the 2 X 6 or 2 X 4 beams forming the laterally'extending reinforcing means 54 at spaced longitudinal positions between side walls 38 and 40 of the improved truss panel 2 X 4s may also form additional reinforcing members between the edge walls or stud flanges 70 and 72; one such lateral reinforcing member being shown at 96, adjacent edge flap 76 which lies at right angles to side wall 68. 2 X 4s or similar wooden beams may extend between the stud flanges of the side panels, at spaced vertical positions to give greater structural integrity and act as a base for fastening interior finishes to the side walls if necessary or desired. Again, staples or their mechanical equivalent may be employed to fasten the 2 X 4s in position and the paper board thereto.

Of importance to the invention is the fact that the optional interior flaps 42 and 74 for the side wall panels and the roof trusses of appropriate length may be formed integral with either side walls 38 or 40 for the roof truss panel, or edge walls 70 and 72 for the side wall panel 24 and may be maintained in open position during initial installation but closed after installation of the plumbing fixtures, electrical fixtures or the like. Further, as illustrated in FIG. 1, two series of side abutting modular roof truss panels are positioned in end abutting, oppositely directed arrays, such that panel tabs 44 and 42 for respective panels abut each other at the center of the building and define a four-ply king post of high structural integrity in a position where the load acting on the roof is at a maximum, that is, between the points of suspension defined by spaced side walls 24.

Referring again to FIG. 3, the use of improved fasteners forms part of the-present invention and is illustrated as being applied to a connection between flap 62 of a roof truss panel 28 and center wall 68 of side wall panel 24. This connection is illustrated in FIG. 10 in terms of a pair of oppositely oriented and oppositely directed fasteners formed from a strip of metal and each being provided with a barbed arrow projection or prong 112 and a specially formed opening ll4 at identically spaced longitudinal positions as illustrated in FIGS. 9 and 10. The metal strip, which may have a length equal to the longest dimension of either panel 28 or 24, is provided at spaced longitudinal positions with struck out projections or barbed prongs 112 having pointed ends 116, serrated edges defining barbs 118, formed by right triangular teeth. The barbed prongs 112 project at right angles as indicated in FIG. 10, while struck out resilient fingers are oppositely directed and have triangular edges which define with the side wall an opening which is hexagonal in configuration and which permits entry of the barbed prong 112, but during any attempt at retrograde movement causes the flexible fingers 120 to bind within the valleys defined by the serrated teeth to resist pull out. Thus, once force is applied in opposite directions as indicated by arrows F1 and F2, in FIG. 3, the multi'ply fiber board sections shown in dotted lines are urged towards each other and securely lock in planar abutting position. Preferably, epoxy adhesive or similar glue or the like (not shown) is liberally spread on the surfaces to be joined prior to use of the strip metal fastener 110 of the present invention. The projections 112 have sharply tapered ends 116 which readily penetrate the paper board and thus form holes by penetration during usage. Exact alignment of connector strips isnot necessary and minor variations in alignment will still permit the projections 112 of .the fastener strip 110 on one side to pass through the holes 114 on the opposite side and vice versa. The projections 112 may be covered by a large board 162.

An alternate form of a fiberglass reinforced, paper board building of the present invention is illustrated in FIGS. 11 through 15 inclusive. While the end wall or side wall panels and the roof truss panels of the building are formed in a generally similar manner to that of the In that regard, the building again consists of a preformed cast concrete foundation having an integral floor slab 12 with the outside edges of the same recessed at 14' and carrying a wooden mounting plate 16 which again may be a 2 X 4 board or the like. A modified side wall panel 24' is shown in FIG. as resting on the plate 16' and being coupled to the foundation in a somewhat similar manner to the previous embodiment. Further, each side wall panel 24 supports, preferably of equal width, a roof truss panel 28 which in this case does not terminate at its outer end in a box overhang, the building being provided with a specially formed and completely separate overhang panel 122.

Turning to FIG. 11, each modified roof truss panel, in this embodiment, is formed from a single sheet 34 of specially treated fiber board and comprising in terms of scored fold lines as indicated by the dotted line in FIG. 11, or a roof portion or center wall 36' of rectangular configuration, with trapezoidal side walls 38' and 40' extending along respective sides of center wall 36'. In this embodiment, the optional ceiling flap has been eliminated although of course one may be added thereto in the manner of FIG. 6. At the right hand or inboard end of the roof truss sheet 34, contiguous scored fold lines define integral tabs 44', 46' and 48' in identical fashion to the previous embodiment. The roof truss panel thus formed by sheet 34 is modified at the left hand end, FIG. 11, from the embodiment of FIG. 5', in that scored fold lines define tabs 124 in conjunction with trapezoidal side walls 38' and 40, while the center tab 126 is an extension of the center wall or roof 36'. Tab 126 therefore acts as an end wall for the panel 28' formed thereby with tabs 124 being bent at right angles to respective side walls 38 and 40' and lying flush with and on the inside of end wall 126 as illustrated in FIG. 15. Staples and waterproof epoxy cements or the like couple respective tabs together to form an open bottom roof truss panel 28'.

To impart structural rigidity to the building and, in particular, to assist coupling of roof truss panel 28' to underlying vertically oriented side wall panel 24', a specially formed roof panel'and wall panel connector of U-shaped configuration, is employed as illustrated perspectively in FIG. 14. This connector 128 which may be formed of fiberglassed fiber board or metal, is U-shaped in configuration consisting of a base 130 and right angle end walls 132, the end walls being coupled respectively to side walls 38' and 40"0f the roof truss panel 28, while the base 130 in this case is fixed to the upper end of side wall panel 24', FIG. 15.

The side wall panel 24' is of modified form and, again, is formed of fiberglass reinforced, resinimpregnated or coated paper boardand reference to FIG. l2,'illustrates a sheet of this material carrying the score lines as indicated by the dotted lines prior to set When wall portion 134 is bent at right angles, it defines the top end or upper end wall of the side wall panel 24', while center wall extension portion 136 is bent at right angles to wall portion 134 while the tabs 138 carried thereby are bent at right angles and inwardly of panel wall extension portion 136 and are fixedly attached to the stud flanges or edge wall 70' and 72' as readily seen in FIG. 15, such coupling being achieved by waterproof epoxy cement and/or staples or the like. When the interior wall flap 74' is bent into a position at right angles to the stud'flanges 70' and 72, and overlies center wall extension portion 136, this completes a box like side wall panel of high structural integrity.

At the bottom of panel 24', sheet 66' is scored and cut to form a center wall extension portion or flap 140 and the panel side walls 70! and 72 are provided with tabs 142 to effect insofar as the corners of the box panel 24' is concerned, overlapping or multilayer base portions to permit fastening of the side wall panels 24 to mounting plate 16 in a manner somewhat similar to the prior embodiment. Anchor bolts 86', FIG. 15, extend upwardly above the upper edge of plate 16 with the ends of the anchor bolts being buried in the foundation side walls 22'. Again, the threaded ends pass through, at least, the side wall panel center wall extension 140 and also through a transversely extending mounting board 144. Coupling is completed by means of a threaded nut 88' and the underlying washer 90'. Since there may be difficulty in bending the fiberglass, resin impregnated or coated paper board sheet at angles greater than 90 without weakening the wall portion in the areas of the score lines, the embodiment of FIG. 15 may be employed rather than the 180 reverse turn provided by the embodiment illustrated in FIG. 4. Resin impregnated reinforced fiberglass mat 91 spans the joint and covers the wall plate 14 and is affixed in the field to insure a watertight, weathertight seal.

The second embodiment of the present invention is highlighted by the employment of a single, unitary overhang panel 122 which is formed from a precut or configured paper board sheet 147, FIG. 13, which is also prescored in the manner indicated. The overhang panel is generally rectangular in form and consisting of up, but after machine stamping or cutting. The sheet 66' of paper board is precut with the scored fold lines defining a center or side wall 68' which faces the exterior of the building and having edge walls and 72' on either side thereof, forming stud flanges with, in this case, optional interior wall flap 74' being provided, in the same manner as the previous embodiment. At the upper end of the sheet 66', there is defined by scored fold lines center wall extension portions 134 and 136 in that order. The extension portion 136 also is provided with integral tabs 138 on either side thereof.

a top or center wall 148,-side walls'l50 and 152. A bottom wall or soffit 154 anda ceiling attachment flap 156. The ends of sheet 146 carry tabs 158 for side walls -l50 and 152 and have at each end a center flap or extension 160. Two such panels form, appropriately, soffit overhang panels at opposite sides of the building. When overhang panel is attached to the building as illustrated in FIG. 15, after set-up, side wall 150 is fastened by staples, specially formed fasteners 110, and/or by means of waterproof epoxy adhesives or the like to end wall 126 of the roof truss 28, while panel portion 150 acts as an extension to the roof center panel 36'. End wall 152 extends the length of the building to define the facia while panel wall portions 154 which act as a soffit, has tab l56 at the inboard end of the same affixed to the upper end of side wall panel 24. Alternatively, staples or fasteners may be employed for this purpose, and it is covered with a large board 162. In other respects, this embodiment is similar to the earlier described embodiment.

Front and rear panels are identically formed and moved into position once the roof truss panels are flush mounted to form the four-ply king post 98 as evidenced in FIG. 1 and the interior panel walls which are hinged be readily constructed in this manner in which the excessive amount of space and are therefore highly costly to ship in preassembled form. On site construction can be made by persons of limited skill for added savings in the construction of commercial and residential buildings. The sheet material forming the panels may be treated after die cutting to insure that the panels are weather resistant, fireproof or fireresistant, and may have the exterior surfaces precoated or otherwise treated, so that no exterior finishing is required once the panels are set up and assembled in serial abutting fashion.

Yet another form of a fiberglass reinforced, paper board building of the present invention is illustrated in FIGS. 16, 17 and 18. Contrary to the prior embodiments, both the side wall panels and the roof panels are identical in all respects, allowing maximum simplicity in design without compromise with the necessity of the panels them selves properly supporting loads at the load centers defined by the end abutting connections between the individual panels. A pre-formed cast concrete foundation 110 carries at each edge, wooden mounting plates 1 16, which may consist of 2 X 4 boards or the like. Side wall panels 124 are edge coupled to each other in side abutting fashion to form a series of side walls which in turn support identically configured but oppositely oriented roof panels 128, the series of side wall and roof panels being end to end, butt connected to form, with the exception of the building end walls, a complete building structure.

In this regard, each of the panels 124 and 128 are identical, and for illustrative purposes, the panel shown in FIG. 18, which is designated as a side wall panell24, is formed from a single sheet 134 of specially treated fiber board which is fiberglass reinforced and resin impregnated or treated, sheet 134 comprising in terms of scored fold lines indicated in dotted line fashion, of a center wall 136 of rectangular configuration and being provided with trapezoidal side walls 138 and 140 which extend along respective sides of the center wall 136. At each end of center wall 136, there are provided center wall tabs 126 and 128 which are rectangular in configuration as defined by scored fold lines, while at respective ends of the side walls 138 and 140, there are provided trapezoidal tabs as defined by scored fold lines which extend inwardly of'the right angle fold lines for the center wall 136, thus tabs 142 and 146 are integral with side wall 138, while tabs 144 and 148 are integral with side wall 140. Tabs 142 and 144 are of a length one-half the width of the center wall tabs, such that, when the side walls 138 and 140 are folded at right angles to the center wall 136 and in the same direction, while the tabs are all folded at right angles to their walls, the tabs 142 and 144 lie flush with tab 126 which overlaps the same, and with the ends of the tabs in abutment as illustrated in FIG. 18 to produce essentially a two-ply end wall of increased strength, imparting structural rigidity to the building illustrated in FIG. 16, especially when the panels of the individual series are fastened to each other in end abutment as illustrated. The fastening techniques employed in the previously described embodiments are employed in the construction of the building partially illustrated in FIG. 16.

It is to be especially noted that since the side walls 138 and are identically configured, but oppositely trapezoidal, there is produced for each panel a large end and a small endj Further, in the construction of the building of the type illustrated in FIG. 16, the large ends of the sidewall panel are fastened in abutment to the large ends of one of the roof panels 128, while the small ends of the roof panels are fastened together to define the center line of the roof. Further, the small ends of the side wall panels are fastened to the mounting plates 114 forming a portion of the horizontal support surface defined by the cast concrete base or foundation 110. Since the ends of all panels are two-ply for structural ridigity, and since further the large ends of the series of abutting panels 124 and 128 abut each other, there is formed a girt connection at 150', these connecting areas forming load centersof maximum structural integrity at their areas of need. The lighter loads at the center of the building are well taken care of by the roof panel center line connection 152.

A further embodiment is illustrated in FIGS. 19-22, which is highlighted by the employment of identical side wall and roof panels. In this case, two series of side wall panels 224 cooperate with a series of roof panels 228 to form a basic building structure completed at the ends by appropriate rectangular or modified rectangular front and rear panels 260, or the like.,A preformed, cast concrete foundation 210 having an integral floor slab 212 carries along the outside edges, wooden mounting plates 216. Side wall panels 224 have one end resting on the plate 216 and are suitably coupled thereto while opposite ends are fastened in abutting fashion to the inclined ends of the similar roof panels 228. The length of each roof panel 228 may be the same, or longer than that of the side wall panels 224 to which it is attached. Of course, a seriesof side to side abutting, end fastened side wall panels 224 cooperate with a series of roof panels similarly coupled to form the roof. and side walls of the building. In that respect, reference to FIG. 20 shows a single sheet 234 of specially treated fiber board, preferably fiberglass and resin coated or resin treated to impart'weather and water resistance necessary to extended use of the building under adverse weather conditions. The single sheet 234 of fiber board is cut to the configuration shown and is provided with scored fold lines as indicated by the dotted lines to define a roof portion or center wall 236 for the panel, of rectangular configuration, trapezoidal side walls 238 and 240 extending along respective sides of center wall 236 and an optional ceiling flap or side wall panel inner wall flap 242 of rectangular configuration and integrally joinedto the outside edge of side wall 240. Both ends of center wall 236 are provided with integral tabs 244 of rectangular configuration, while the side walls 238 and 240 are provided, at each end, with trapezoidal tabs 246. The configuration of tabs 244 and 246 and their method of being folded at right angles in mutually overlapping fashion are in all respects identical to the arrangement illustrated in the embodiment of FIGS. 16 18, the inclination of the scored fold lines defining tabs 240 being such as to define angularly inclined end walls to create an elevational configuration as seen in FIG. 19 when two series of end wall panels 224 are joined by a series of horizontal roof panels 228 in end to end abutting fashion.

To complete the structure, the front and rear of the building are provided with rectangular or modified rectangular panels 260 which are formed from flat sheets illustrated in FIGS. 21 and 22.

The interior wall 242 is bent at right angles along the score line separating the side wall 240 and wall 242 with the edge 248 of this wall extending beyond a free edge of side wall 230 after bending and connecting the tabs 244 and 246 together so as to define a completely boxed panel either as a roof panel 228 or side wall panels 224.

The small rectangular panels 226 appearing immediately above the windows 268 and door 270 in the embodiment of FIG. 19 are formed in a similar manner to the prior described panels from a single sheet 274 of fiber board and comprise in terms'of scored fold' lines of a center wall 276 and identical, rectangularly configured side walls 278 and 280; the center wall 276 provided with rectangular tabs 284 at each end defined by scored fold lines while contiguous scored fold lines define trapezoidal tabs 282 at respective ends of side walls 278 and 280. The side walls 278 and 280 are bent in the same direction at right angles to center wall 276 along the fold line, while tabs 284 and 282 are also bent at right angles to respective panel walls 276 and 278 and the mutually overlapping tabs are fastened to each other to form multi-ply ends assisting in the structural integrity of the completed building of FIG. 19. Again, windows 268 and their method of attachment to the end wall and the mounting of door 270 are conventional and form no part of the present invention. Because end walls 224 are inclined, it is necessary to modify the structure of front and rear panels 260, evidenced by panels 262 and 264, panels 262 being trapezoidal in elevation, while panels 264 are triangular in elevation. In fact, the panels 262 and 264 may be formed by appropriately configuring and cutting a single sheet such as sheet 290 illustrated in FIG. 22. The sheet includes longitudinal score lines 292 defining side walls 294 and 296 for panel 262 and a side wall 298 for panel 264, at the same time defining center wall portions 300 and 302 for panels 264 and 262 respectively. Irregular, oblique cutting lines 304 and 306 permit severance of the sheet into two portions, the right hand portion forming panel 262 and the left hand portion forming panel 264. In each case, tabs 308 and 310, similar to tabs 280 in the FIG. 21 panels, and tab 312 for panel 264 and 314 for panel 262 are formed as extensions of the side walls of these respective panels. The folding of the side walls and the tabs at the bottom ends of panels 262 and 264 may be readily envisioned by reference to the prior embodiments. Panels 226 are formed by diagonally slicing a panel 260, forming duplicate halves. It is sufficient to state that the tabs 314, for instance, are connected in overlapped face to face fashion to impart increased structural rigidity to the front and rear panels forming portions of the building of FIG. 19. In like manner to the previous embodiments, the material forming the modular panels 224 and 226 as well as the front and rear wall panels as at 260, 262, 264 and 267, may consist of a corrugated board formed of paper or the equivalent, suitably waterproofed as being fiberglassed and resin impregnated or resin coated or by other similar means. In the illustrated embodiment in FIG. 19, the end wall series of panels allow the panels 224 to employ multi-ply ends which abut and are fastened to the foundation 210, in particular the upper surfaces of the plates 216. Further, a four-ply connection occurs between the inclined ends of the roof panels 228 and the upper ends of the horizontally positioned roof panels 228 where they meet the abutting inclined edge of the side wall panels 224. Since natural load centers occur at the junction of these panels the structural integrity of the completed building is assured, while the multi-ply panel ends further assist in retention of the fastener means coupling the ends of respective panels. The interior wall 242 may be readily folded into position and fastened after plumbing, electrical wiring or other elements necessary to the completion of the building are installed within the ceiling and side wall panels. The coupling of respective side wall panels to each other and to the foundation are in terms previously described with respect to the other embodiments of the invention, although the free ends of the triangular and trapezoidal panels underlie the side walls 238 for instance of panels 224 and are directly stapled thereto.

It is, however, intended that the various changes and modifications may be made within the scope of the invention as defined in the appended claims.
